Under the Amendments, we paid the Holders an aggregate amount equal to $500,000 (representing 50% of the outstanding principal balance of the Notes) plus all accrued interest on the Notes. In consideration of the foregoing, the Holders agreed to, among other things, extend the payment date of the remaining 50% of the outstanding principal balance of the Notes from October 17, 2017 to the earlier of May 18, 2018 or the closing of our next underwritten public offering of securities in which we raise gross proceeds of at least $3,000,000 (should we elect to commence and close such an offering of securities). |  |  |  |
